News RTX 4090 liquid cooled with 12,000 BTU air conditioner, RTX 5090 up next — GPU runs at 20C

[Admin]

A Chinese techtuber has designed a liquid-cooled PC system that hooks up to a household air conditioner unit instead of a PC-mounted radiator.

I'm still waiting for someone to build a pc in a mini refrigerator.

I'm still waiting for someone to build a pc in a mini refrigerator.

That cannot work because the refrigerator is a very bad environment for electronics (humidity, condensation). What this guy did is good because the PC is still in the room in optimal environmental conditions and only the liquid coolant goes to the AC unit. It's how modern data center cooling work by the way, he didn't invent anything.

A fridge works on the same principles as AC, except it's significantly less powerful.
We're talking like maybe 60W peak to run the compressor on a fridge, and it isn't designed to run 24/7.

Where as an AC is at least 600W and designed for 24/7.

My Chinese is not so existent, but looking at the video, i'm thinking that's satire.
BELIEVE it or NOT: people in other cultures also have a sense of humor.

Its not like something a little bit like this hasn't been done before.

At Computex, Intel Demos A 28-Core Processor Clocked At 5GHz (Updated)

Why would it be satire? Sub-ambient cooling with evaporative loops is as old as custom PC watercooling (back when DIY was the only option). It was a 50/50 mix between people repurposing fridge/freezer compressors and using AC unit compressors.
However, this particular build is not even a subambient chiller, but harkens back to the DIY watercooling staple of repurposing existing radiators. The radiator loop of the AC unit has been replumbed to cool a water loop directly, with no refrigerant or phase-change involved.

That's been done many times.
It does not work well. The fridge dies very soon.

There is no compressor where it should be. It's using the condenser coil as a radiator. There is no refrigerant involved at all. Looks stupid. Just a big ugly radiator. This does NOT use Air Conditioning. Stupid Clickbait. WTF!

If the fridge interior has fan assisted cooling, as many modern fridges do, most of the moisture in the air is deposited on the heat exchanger and exits through a drain. So, if the door is kept closed, humidity will be kept low. As stated above though, the fridge won't last long as they are not designed for long periods of continuous operation.

So in the end, its just a big radiator with a big fan. Now do the same with with proper flare fitting and a working compressor, I am prety sure they could achieved well below zero levels

LInus tech tips has all kinds of stupid videos on this topic. They have tried many silly thing including using a swimming pool to cool servers. They also actually used some kind of water chiller that is basically a AC unit that cools the water. In the end they do it for the views on their youtube videos it is not really something someone does.

Yes that's true, but too low humidity is as bad as too high for computers. I'm pretty sure maintaining a safe humidity level inside a box that is at 2c with a space heater running in it would be quite a challenge. It's why data centers always keep their server rooms at a regular 20-21c temperature and evacuate the heat from the computers through chilled water loops.

And of course, if you put a 4090 into a Whirpool beer fridge it's not going to last very long (it actually won't work at all since the temp will quickly go up until the compressor fails). But when I read the comment I assumed that the person who would try that would think about a more robust system than a regular refrigerator.

No, people have tried that. Without thinking through al the problems.

Why Are PCs Not Housed in Mini Refrigerators?

I was just wondering why pc motherboards and everything connected to them would not be housed in a mini-fridge. it would be nice to see all the pc innards easily accessible just by opening a double-door (French doors) to add or upgrade cards, hard drives, and memory. I could totally see Whirlpool...

Yeah guys. This isn't cooling with a 12k BTU air conditioner. It's just using the coils and fan of the compressor as a giant radiator.

I know low humidity can contribute to ESD, such that places with exposed electronics components (labs, manufacturing floors, etc.) are often humidity-controlled environments. What are the concerns with low humidity a fully assembled PC?
